Description

FIELD OF THE INVENTION The present invention relates to an outer race having a ball raceway distributed in a generally longitudinally extending circumferential surface, and an advantageously non-undercut ball distributed in a generally longitudinally extending circumferential surface. An inner race having a track, said two tracks being in pairs radially facing each other and each receiving a common torque-transmitting ball, and A cage which receives the balls in windows distributed in the circumferential surface and which has a common
When held in one plane and the axes of the outer and inner races are bent relative to each other, the ball lies on a plane that forms one half of the bending angle, and The race is manufactured with an inner surface which is not undercut in the axial direction of the curve of the respective ball track, and further comprises at least three fixing members for the cage in the outer race, each of which has two Is inserted between the two ball raceways and is connected to the outer race, and the fixing member forms a cage abutment surface or a cage guide surface that reacts from the outer race to the axial movement of the cage. , A ball-type synchronous rotary joint of the type which allows the ball to move between fixed members.

BACKGROUND OF THE INVENTION The present invention has been applied to various types of ball-type synchronous rotary joints, and in particular, so-called RF-joints (Rzeppa).
-Fixed joint] and so-called UF-joint [undercut-free-joint]. This type of joint is available from F.
F. Schmelz, inter alia “Fittings and fitting shafts: Gelenk und Gelenkwellen: quotation, construction and use”
This feature was described in Berlin, Heidelberg, New York 1988, where the control of the cage was not caused, or not exclusively by the shape of the cage guide surface, but firstly the outer race and the inner race. Produced by the shape of the ball track in the race, these center lines being offset from each other, but extending symmetrically with respect to the plane defined by the ball center when the joint is extended.

Couplings of the type mentioned are known, for example, from German patent DE 2430027.

21 is a side sectional view thereof, and FIG. 22 is a sectional view taken along the line II-II of FIG. 20. For explanation, 71 is an outer joint member, 72 is an inner joint member,
73 is a ball track of the inner joint member, 74 is a ball for torque transmission, 75 and 78 are shafts, 76 is an outer joint, 77 is a cage of balls, respectively, and a cage fixing member 79 is inserted in the axial direction. . Such a fixing member has a drawback that it obstructs the movement of the ball when the joint is bent and restricts the bending angle.

If a side sectional view of the invention of German Patent No. 3626998, which is another known example, is shown in FIG. 23, 81 is an outer joint, 82
Is an inner joint, 83 is a ball raceway of an outer joint member, 84 is a torque transmitting ball, 85 is a shaft, 86 is a ball raceway of an outer joint member, 87 is a cage of balls, respectively, and a fixing member 89 is an outer joint member in the middle. It is fitted in the ring-shaped groove 89A. The fixing member 89 and the ring groove 89A form a conical angle of the corner 22, and the fixing member 89 and the cage 87 form a conical contact surface 89C.

This type of securing member does not allow adjustment of play in the cage to compensate for errors.

Furthermore, since the fixing member limits the movement of the ball and the inclination of the shaft fixed to the inner joint member, the bending of the joint is limited.

In FIG. 24, which is a side sectional view of a joint shown in German Patent No. 2522670, which is a third known example, 91a is an outer joint member, 91b is a base portion having a shaft 95, and 92 is an inner joint member. Reference numerals 93 and 96 are ball raceways, 94 are balls for torque transmission, 97 is a ball cage, 95 and 98 are shafts, and members 91
The a and 91b are fixed by screws 91c.

In this example, the cage 97 is supported by a ring-shaped fixing member 99. The fixing member with this inwardly deformed tongue also limits the bending of the joint and, since it must be pre-deformed, axial play adjustment is not possible.

DISCLOSURE OF THE INVENTION The subject of the invention is that the maximum bending angle is unaffected by the fixing member for the cage and that the fixing member can be used for adjusting the axial play in the cage. To provide a type of fitting. A solution for this is a key in which the fixing member is axially inserted independently of each other in the annular gap between the outer race and the outer surface of the cage and welded to the outer race, which key is , Holding the cage in the outer race with adjusted axial play at the point of contact A. For example, in a joint with 6 balls, 3 with 2 ball tracks each in between.
The four fixing members are evenly distributed and arranged on the peripheral surface.

In this case, in an advantageous manner, the cage is introduced into the outer race before incorporating the fixing member with its axis lying coaxially with the axis of the outer race, and then the fixing member is placed in the outer race. And combine with this. Therefore, complicated insertion of the cage into the outer race can be dispensed with. In this case, the inner race
As already mentioned, it can already be pre-assembled with a cage and, at the same time, can be coaxially put together with the cage in the outer race. In an axially undercut-free track towards the opening of the outer race, the balls are also already pre-assembled in an assembly group with cages and inner races, which balls together with the outer race. Can be put inside. at the same time,
The entire joint can be adjusted axially without play, or with a certain amount of play, depending on the assembly type, independent of manufacturing tolerances.

In an advantageous configuration, the radius of curvature of the track has an axial offset with respect to the plane E _K through the ball center when the joint is extended, and in addition the inner race offset O ₁ Outer race offset at O ₂
You can be different from. For this reason,
The control of the cage during joint buckling is done primarily via the ball track and the ball, so that the cage can be constructed with a relatively light and uniform wall thickness.

One embodiment of the present invention is that the inner surface between the tracks in the outer race forms a cage abutment surface or cage guide surface against which the cage abuts. It is to be supported axially inward in the outer race at point E. This shows a particularly simple shape of the axial fixation of the cage.
As mentioned above, the fixing member can be welded directly to the abutment with the cage, or after adjusting the slight axial play, optionally before the axial direction to the cage. The reference position is found by applying the.

In another configuration of the above embodiments, the inner race is
Axially inwardly supported in the outer race via its outer surface on the inner surface of the cage and axially outward in the outer race via its track at the ball and thus the ball and cage. Can be supported indirectly via the fixing member.

In contrast to this, the inner race is axially inward and outward, in the outer race via the respective outer surface at the inner surface of the cage and thus indirectly through the cage and the fixing member. Can be supported.
For this reason, support via the cage window is omitted.

In this case, despite the aforementioned shape of axial support,
The balls are retained in the outer race and inner race tracks in a substantially radial, play-free manner when the cage is retained in the outer race in a play-free manner.

After fixation of the cage, namely to eliminate the movement and oblique support after fixing of the fixing member, the center point M _1, M ₂ of the cage contact surface or the cage guide surface of the fixed member and the outer race joint extended The cage contact surface or the cage guide surface has radii R ₁ and R ₂ longer than the radius R of the outer surface of each cage. Has become.

A second embodiment of the invention is that the inner surface between the tracks in the outer race has a radial play S ₃ with respect to the outer surface of the cage, and furthermore the inner surface of the cage is Contacting with the outer surface located between the raceways at contact points D and further axially inward at the contact points B on the flange where the cage faces the opening of the outer race through the cage window It is characterized in that it is supported by a ball, and the ball itself is supported by contact points C ₁ and C ₂ on the outer race and inner race tracks.

Once again, the assembly is guided until it has produced full axial play freedom as described above, or is used to adjust the desired axial play, again here.
To find the reference position, the axial play is first set to zero. In the axial play freedom, the support limits the abutment of the ball in the track and at the same time gives the ball radial play freedom.

Such contact between the ball and the track occurs at the bottom of the track. However, double ball contact is also possible on the flanks of each track, depending on the track cross-sectional shape.

In another configuration of this embodiment, there is a radial play S ₁ between the inner surface of the cage and the outer surface of the inner race on the side facing the opening of the outer race. Further, when the ball abuts on the contact points C ₁ and C ₂ on the track and the contact point B on the flange of the cage window,
There is an axial play S ₂ to the cage window flange towards the inside of the outer race. For this reason,
The raw part of the picture in the lace and cage can be increased. According to an improvement which is advantageous for both of the above-mentioned variant embodiments, the inner surface of the outer race has an inner surface which is beyond this plane in the area of the plane passing through the center of the ball when the joint is extended and which faces the interior of the outer race. It has a cylindrical section. This makes it possible to prevent radial movement of the cage in the axial assembly which has already been repeatedly described previously, since the cage abuts against this inner cylindrical plane. Moreover, the tendency of the outer race to deform under torque loading can be limited by the outer race being supported by the cage over the inner cylindrical surface.

Due to the advantageous construction, the ball raceways in the outer race and the inner race are axially undercut-free when viewed from the opening side of the outer race, so that the balls are already also pre-assembled with the inner race and the cage The assembly advantage is obtained in that it is possible and that this assembly group can be axially put into the outer race before the final assembly of the fixing element. In the case of a joint according to the invention, the length of the window of the cage is defined by the passage of the ball relative to the cage, viewed in the circumferential direction as the joint bends, which increases with the bending angle, so that The length of the window in the circumferential direction can be limited. In short, the window length in the circumferential direction must correspond only to the passage in which the ball is circumferentially configured with respect to the cage when the joint is bent and rotated under the operating angle. For this reason, the inner race and outer race axes are repeatedly bent to an assembly angle at which one cage window can freely come out of the outer race, thereby allowing each one ball to be radially entered. Can be avoided.

Due to the unique design of the fixing member, play compensation is possible for the cage such that the axial fixing can be adjusted individually and independently of each other, and thus the surface of the fixing member and the outer surface of the cage. It also provides uniform support between.

By virtue of an advantageous construction, the fixing member is a simple key which is introduced into the ring-shaped surface of the outer race, by means of which it abuts against the pre-loaded cage and possibly joins it with the outer race. Only axial play adjusted before doing. In this case, the inner side of the key facing the cage has an inner ridge or inner key shape for contacting the outer spherical cage.

In another configuration, the outer and
A pocket or a notch is formed in the race, and the fixing member engages with the notch in a shape-fitting manner in the circumferential direction. In this way, the circumferential position of the fixing member during assembly is easily maintained.

In a further advantageous arrangement, the cutouts are adapted to allow axial and / or radial movement of the fixing element within the outer race before the fixing element is connected to the outer race. As a further advantageous configuration, the outer race may be a longitudinal groove which is inclined at an angle with respect to the axis, in which case the fixing element can be wedge-shaped as already mentioned.

With a particularly advantageous design, the outer race is manufactured as a sheet metal molding with a substantially constant wall thickness. In this case, it is particularly advantageous if the parts thus produced by deep drawing are completely undercut-free in the axial direction, in which case the individually welded axial fastening members axially move the cage. To support.

BEST MODE FOR CARRYING OUT THE INVENTION FIGS. 1 and 2 show one joint each having an outer race 1a, which on one side has a joint bottom 2a to which a pin 3a is connected. And has an opening 4a on the opposite side. The inner surface 5a of the outer race 1a is not axially undercut when viewed from the opening 4a, which also applies to the circumferentially distributed ball tracks 6a. In the outer race 1a is placed a cage 7a having a spherical outer surface 8a, which is supported axially inwardly at the contact point E on the inner surface 5a of the outer race, And axially outwardly, it is supported at the contact point A by a plurality of fixing members 9a which will be described in more detail. The cage has a spherical inner surface 10a in which an inner race 11a is guided by a hemispherical outer surface 12a. A vertically extending track 13a in the inner race 11a
Is formed, and the track is still not undercut when viewed axially from the opening. Balls 14a are retained in the tracks 6a, 13a and are axially supported by windows 15a in the cage. The plurality of fixing members 9a are inserted into the wedge-shaped guide grooves 17a in the outer race and have a spherical inner surface 16a. The axis of the wedge-shaped guide groove is inclined with respect to the longitudinal axis of the outer race, so that a radial access to the cage takes place at the same time as the fixing member moves axially within the guide groove. As can be seen in plan view, the fixing member is joined to the outer race by a weld seam. In the longitudinal section, the front chamfer 9S is chamfered obliquely, which chamfer is at least aligned with the corresponding chamfer 1S of the outer race opening, as shown in FIG. 2, when the joint is bent. The fixing member does not interfere with the shaft fixed to the inner race.

In Figure 2a, the outer race 1a, the inner race 11a,
One of the cage 7a and the fixing member 9a is shown in an enlarged longitudinal section. The cage is the outer one between points E and A.
In contact with a race or a fixed member. The center points M ₁ and M ₂ of the spherical cage abutting surface or cage guide surface of the fixing member 9a and the outer race 2a are relatively to a plane passing through the ball center E _K when the joint is extended. It can be seen that they are offset in opposite directions in the axial direction, and that the radii of curvature R ₁ , R ₂ of the spherical surfaces are approximately the same length and slightly longer than the radius R of the outer surface of the cage 7a. Furthermore, it is clear that the inner surface of the outer race 1a is constituted by a cylindrical part extending over the section Z from the plane E _K passing through the ball center when the joint is extended to the inside of the joint. Since the outer race is undercut free, this inner cylindrical surface transitions to the outside of the outer race having at least the same diameter.

The symbol O ₁ indicates the so-called offset, that is, the axial distance of the center point of the radius of curvature of the raceway 13a in the inner race, which is not shown in detail, with respect to the plane E _K passing through the joint center, that is, the ball center, and the symbol O ₂ indicates , The center of the radius of curvature of the track 6a in the outer race with respect to the joint center, i.e. the plane E _K passing through the ball center when the joint is extended, corresponds to an offset which is different from the aforementioned offset in some cases .

In FIGS. 3 and 4, the same members as those in FIGS. 1 and 2 are enlarged and shown with the same reference numerals.

In FIGS. 5 and 6, members corresponding to those in FIGS. 3 and 4 are shown with the same reference numerals but with “b” added. Here, unlike FIG. 3 and FIG. 4, a groove 17b having a wedge-shaped cross section is formed.
However, when viewed in a vertical cross section, it has an axis-parallel extension with respect to the contact surface between this groove and the fixing member 9b.

In FIGS. 7 and 8, members corresponding to the members in FIGS. 3 and 4 are shown with the same reference numerals with “c” added. As can be seen from FIG. 8, the construction of a special guide groove for the fixing member 9c is omitted here. As far as this is concerned, there is also no circumferential guide for the fastening element. For this reason,
The cutting method in the outer race can also be omitted.

9 and 10, members corresponding to those in FIGS. 3 and 4 are shown with the same reference numerals but with a "d". As can be seen in the plan view according to FIG. 9, the guide groove 17d for the fixing member 9d is constructed with a rectangular cross section,
The groove is manufactured similar to the groove in FIG. 4, which has an axis-parallel extension as can be seen in longitudinal section.

In FIGS. 11 and 12, members corresponding to those in FIGS. 3 and 4 are shown with the same reference numerals but with “e” added. Unlike FIG. 3 and FIG. 4, the vertical cross-sectional view according to FIG. 12 shows a guide groove 17e having a rectangular horizontal cross section. As a result, the fixing member 9e simultaneously approaches the cage 7e in the radial direction when moving in the axial direction.

13 and 14, members corresponding to the members in FIGS. 3 and 4 are shown with the same reference numerals but with "f" added.

Unlike FIG. 3 and FIG. 4, as can be seen in FIG.
It shows a groove 17f of rectangular cross section whose axis, and thus its base, extends at an angle towards the central axis of the joint. As a result, the fixing member 9f simultaneously approaches the cage 7f in the radial direction when moving in the axial direction.

Parts corresponding to those in FIGS. 3 and 4 are shown in FIGS. 15 and 16 with the same reference numerals but with a “g”. Figure
At 15, the fixing member 9g is housed in a guide groove 17g, which is restricted to be circular in cross section, the axis of which is parallel to the joint axis. As can be seen from Fig. 16, the axial length of the guide groove is determined by the fixing member
It is sized so that it can be inserted to compensate for play by its innerly located surface that fits in.

FIGS. 17 and 18 show a slightly different coupling compared to FIGS. 1 and 2, in which case the corresponding parts are
Only the added number is attached. Unlike FIG. 1 and FIG. 2, the inner race 31 has a surface of the inner race 31.
Annular gap between 32 and inner spherical plane 30 of cage 27
It has an area that is partially reduced in diameter by 40 to give rise to 40, and thus a radial play S ₁ . The spherical outer surface 28 of the cage is held out of contact with the inner quad-free inner surface 25 of the outer race 21, in which case a radial play S ₃ is provided. The sliding contact takes place on the outer surface 28 of the cage 27 only against the fixing member 29 at the contact point A. Outer race 21
Axial inward support of the cage 27 against the outer spherical outer surface 32 of the inner race at the contact point D, ball 35
The cage window 35 at the contact point B in FIG.
Indirectly via balls 34 supported at contact points C ₁ , C ₂ on race and inner race tracks 26 and 33. When the ball 34 comes into contact with the contact point B of the cage window, a play S ₂ occurs on the opposite side.

The symbol O ₁ indicates the so-called offset, that is, the axial distance of the center point of the radius of curvature of the track 33 in the inner race, which is not shown in detail, with respect to the plane E _K passing through the joint center or the ball center, and the symbol O ₂ indicates , The outer surface of the joint center, that is, the plane E _K that passes through the ball center when the joint is extended.
This corresponds to an offset of the center point of the radius of curvature of the track 26 in the race, which is not detailed here, possibly different from said offset.

FIGS. 19 and 20 show a joint that substantially matches the joint shown in FIGS. 1 and 2, in which case the joints shown in FIGS.
The relationship of the cage guide shown in 18 is quoted. The reference numerals of the corresponding parts are added to the reference numerals of FIGS. 1 and 2, respectively. A further difference with respect to the joint according to FIGS. 17 and 18 is that the outer race 41 is manufactured as a deep-drawing member with a substantially uniform wall thickness, in which case the outer race track 46 has a radial indentation. It is formed by the deformed portion 61. In this case, a shaft 62 is attached to the inner race 51 and is fixed in the axial direction by a fixing ring 63.
